Last Night in Soho is a psychological horror film about a young, naïve fashion student in London named Eloise, played by Thomasin McKenzie. Eloise is so obsessed with the Swinging London of the 1960s that she begins dream of and (sort of) inhabit the body of a glamorous aspiring singer played by Anya Taylor-Joy. The more this happens, the more the wall separating her dreams and her waking life begins to crumble. The film is directed and co-written by Edgar Wright and features the late Diana Rigg in her final film role.
